What is a "Signal To Jammer Ratio"? The Most Authoritative Explanation.

How do you calculate the effect of jamming signal?

The effect of jamming signal depends upon J/S (Jamming to Signal ratio), interleaving, modulation type, channel coding technique of the target system. Jamming to Signal ratio can be expressed by the following equation. J/S = (Pj * Gjr * Grj * Rtr 2 * Lr * Br)/ (Pt * Gtr * Grt * Rjr 2 *Lj * Bj)

What is the J/S ratio for jamming?

J-S Ratio (Monostatic) The ratio of the power received (P r1 or J) from the jamming signal transmitted from the target to the power received (P r2 or S) from the radar skin return from the target equals J/S. Note: To avoid having to include additional terms for these calculations, always combine any transmission line loss with antenna gain.

What is the received signal at the jammer?

Answer: The received signal at the jammer is the same as the example in Section 4-3, i.e. answer (1) = -32.3 dBm @ 5 GHz. Since the received signal is above -35 dBm, the jammer will operate in the saturated mode, and equation [5] can be used.

What is RF signal jamming and how does it work?

As a result of RF signal jamming, the desired wireless signal can not be received or decoded properly at the wireless receiver station. The concept of signal jamming came into existence from military establishment.
